武德九年六月李世民颁布了《二名义不偏讳》诏,这与当时的历史背景及现实需要息息相关。该诏令的发布对唐代社会产生了重大而深远的影响,为唐代避讳定下基调。《论武德九年<二名义不偏讳诏>》一文着重分析了该诏令颁布的时代背景,诏令实施的相关规定,并全面考察了诏令颁布后产生的社会影响及其嬗变。 In June 2009, Li Shimin promulgated the edict of “Two Unrelated Tabernacles,” which is closely related to the historical background and realistic needs of that time. The publication of the edict had a significant and far-reaching impact on the society of the Tang Dynasty and set the tone for the taboo of the Tang Dynasty. On the background of the edict, the relevant provisions on the implementation of the edict are emphasized on the article “On the Eight Departures from Nomination in Nine Decades of Wudu” and a comprehensive survey of the social influence and its evolution after the edict was issued.
